+This example shows how to use the @EJB annotation on a bean class to refer to
other beans.
+
+This functionality is often referred as dependency injection (see
+http://www.martinfowler.com/articles/injection.html), and has been recently
introduced in
+Java EE 5.
+
+In this particular example, we will create two session stateless beans
+
+ * a DataStore session bean
+ * a DataReader session bean
+
+The DataReader bean uses the DataStore to retrieve some informations, and
+we will see how we can, inside the DataReader bean, get a reference to the
+DataStore bean using the @EJB annotation, thus avoiding the use of the
+JNDI API.
